Irradiation of normal tissues at the dose/time factor employed in the treatment of solid tumors impairs the subsequent healing of surgical wounds made in those tissues. Irreversible radiation damage to regional fibroblasts is one cause of impaired healing. This study was conducted to determine whether syngeneic guinea pig fibroblasts, harvested from tissue culture when injected into irradiated guinea pig skin at the time of wound closure, could improve wound healing. Breaking strength determinations indicate that irradiated wounds demonstrate enhanced wound healing if implanted with fibroblasts.

Combined laryngeal conservation surgery and irradiation: can we expand the indications for conservation therapy?

Thirty-nine patients (median age of 60 years) with carcinoma of the supraglottic larynx (N = 16), vocal cord (N = 4), and hypopharyngeal wall and pyriform sinus (N = 19) were treated by combined conservation surgery and radiation therapy. Thirty-three patients had postoperative treatment, and the remaining six were given preoperative irradiation. The plan was chosen because of clinical and pathologic features known to be fraught with a high incidence of recurrence above the clavicles. Long-term complications occurred in six patients, two of whom died of aspiration pneumonia. Thirty-eight patients completed their treatment and have been followed for a median of 48 months (1 1/2 to six years). Survival rates are 56% and 63% for absolute and determinant cases, respectively.
